One of Taylor Swift's latest tracks, "Gorgeous", which is featured on her newly released album, does not officially feature any additional artists. But for weeks, there has still been speculation that another famous voice is featured on the track. Now, after the midnight release of the album, Reputation, we finally know the baby saying "gorgeous" is Blake Lively & Ryan Reynolds' daughter.

In fact, it's their oldest daughter, James.

That fact was confirmed by the album's booklet, which notes "Baby intro voice by James Reynolds" during a portion that features production credits.

The question of who the baby's voice belongs to has been the subject of fan theories since the release of "Gorgeous," which itself came out three weeks before the Nov. 10 release of Reputation.

The latter of those theories can be thrown to the wayside now, though. The baby that can be heard saying "gorgeous" at the beginning of the track is definitely not Taylor Swift and it definitely is Black Lively and Ryan Reynolds' daughter.

The release of Reputation now makes it official.

In the tweet below, you can see a photo that shows the production credit the 2-year-old James Reynolds received.

Before the release of the Reputation, even Swift herself had helped stir speculation around the identity of the baby featured on "Gorgeous," which is the third track on the new album.

After a fan on Tumblr asked the artist who the voice belonged too, the 27-year-old singer responded with three simple words: 300 people know.

Those 300 people are to assumed to have been the fans who attended a private listening party and were apparently let in on the secret long before anyone else.

Sure enough, there were fans online who corroborated that assumption.

"I can't wait for #Gorgeous to be released tomorrow," one of the fans tweet. "It's a masterpiece even by [Taylor Swift's] standards. & I'm not saying who the baby is!"

Swift had used her younger self as a prelude to a song before, on the track "The best day." People who revisited the track — and it's super nostalgic video — reasonably thought that the voice at the beginning of the older song matched the voice at the beginning of the new track, "Gorgeous."

In other words, guessing that the voice belonged to Taylor wasn't at all a bad shout.

As for the content of the song, well, that's been the subject of speculation, too. One particular lyric gave fans reasons to believe that the song was about Calvin Harris, Swift's ex.

That lyric read,

And I got a boyfriend, he's older than us

He's in the club doing I don't know what

Harris is indeed six years older than Swift and, as a DJ, has way more of a reason to be up in the club than, say, Tom Hiddleston.

Another theory raised the possibility that "Gorgeous" was meant as indirect shade towards Kanye West, for a number of reasons. Swift's label had to even go as far as to release statement, clarifying that release date of the album, which matches the 10-year anniversary of the death of West's mother, was a mere coincidence.
